This board works fine. I purchased the normal one…. but the wiring as shown in the video is wrong. This board is capable of running the pump even after we switch off the machine for 20sec approx. to cool down the heater. But in the video switch is directly connected in the mains so when we switch it off whole machine (including air pump) will stop. Instead provide switch between the pin next to live connection in pcb and the pin next to live track. i.e.if live pin is no.1 then provide switch between second and third pin… leave 4 pin open and it will work fine…. now if u switch it off… pupm will keep running for about 20sec and then shut down.
